NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT
The failing WMDRM boundary
NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT is Windows Media DRM HRESULT 0xC00D2795. It identifies the DRM runtime cannot create the migration-importer object required for this operation. The useful scope is the controlled import/export path that packages legacy DRM state, validates the migration image and source identity, and commits eligible licenses to a supported target environment; it is not a generic statement that the media player, network or file system failed.
The built-in message summarizes the user-visible outcome, while the symbolic phrase “unable to create migration importer object” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
Evidence worth preserving
Capture the first NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT occurrence before retry or teardown changes state. The smallest useful record contains:
- Code-specific proof: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- Protected identity: importer plug-in availability and current operation state.
- Operation state: per-license duplicate or import result.
- Persistence or transport: source and target OS versions and user SIDs.
- Security context: migration image identity, hash and creation time.
- Correlation point: legacy V2 secure-store entry and supplied password.
Prefer IDs, hashes, sizes, and timestamps. Never log keys, passwords, licenses, or decrypted media.
The surrounding protocol and store state
Migration is not equivalent to copying license-store files: the importer validates source state, target support and protected identities. A migration image, target-state corruption and an already imported license are independent outcomes and should not be collapsed into one generic restore failure.
Diagnostic sequence
- Locate the earliest API return, callback or event containing
NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECTand0xC00D2795. - Identify the exact content, license, store, device or migration object generation involved in “unable to create migration importer object”.
- Determine whether “unable to create migration importer object” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
- Perform the code-specific check: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- Make one narrow correction — correct component/version or initialization state and create a fresh migration-importer object — and repeat the same producing operation.
Related codes and the diagnostic split
| Result | Different boundary |
|---|---|
NS_E_DRM_MIGRATION_NOT_SUPPORTED | The selected importer plug-in does not support this migration format or operation. |
NS_E_DRM_MIGRATION_INVALID_LEGACYV2_SST_PASSWORD | The password for the legacy v2 secure-store entry is incorrect. |
NS_E_DRM_MIGRATION_LICENSE_ALREADY_EXISTS | The target already contains the license being imported. |
Order the NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT event chain by timestamp; prefer the earliest specific result.
Correcting the producing condition
The corrective direction is to correct component/version or initialization state and create a fresh migration-importer object. Preserve the original content/header, store or migration material for NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT until the operation succeeds and survives a fresh application object or required restart.
Representative case: The application reaches the migration-importer stage but object construction fails before any content or server work begins.
Regression check
After the repair, recreate the WMDRM object and run the smallest reproducer for NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT. Confirm that 0xC00D2795 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it.
What the missing object would have owned
In the NS_E_DRM_UNABLE_TO_CREATE_MIGRATION_IMPORTER_OBJECT path, the migration-importer object normally validates and imports a supported migration image into target protected state. Object creation fails before that responsibility can be transferred to a live interface, so later player or server messages are secondary.
For this object specifically, preserve the importer version, image identity, source format and target store generation. A successful fix should create a new migration-importer object and then complete its first real operation, not merely make the factory call return a different generic error.
